direction to give the high s eed and in :the other direction to give t e intermediate speed. These rock shafts are provided with arms 12 and 13, respectively, which are connected by the links or connecting rods 14 and 15 to the levers 16 and 17, respectively.

These levers 16 and 17 are mounted by ation of the control except as connecting means;

The control post is provided with a lever 27 on its upper end, while the post rock shaft 26 is provided with a lever 28,-see

" Figs. 3 and 6. These posts or rock shafts are arranged one within the other. The lever 27 isv connected to the 0st 25 by means of the sleeve 29, and the ever 28 is connected to the post 26 by means of the sleeve 30. These sleeves are provided with projecting bearing or bushing portions which serve to space and support the concentrically-arranged post tubes. By the shifting of these levers 27 and 28, the clutches, through the connections described, are actuated, the lever 28 being shifted in one direc-' tion to secure the high speed and in the other direction to secure the intermediate. speed, while the lever 27 is shifted to secure the low speed, as described. These levers 27 and 28 are inclosed in the post head or casing 31, which has horizontal slot-like openings 32, 33 and 34-34, the openings 34 being of the same form and oppositely-arran ed; whereas, the opening 33 is slightly mo ified, the purpose of which. will be made clear as the description proceeds.

The levers 27 and 28 are shifted by means of the pivoted shifting lever 35, which is forked at its inner end and mounted on the pivots. 36 carried by the revolubly-mounted collar 37. This shifting lever 35 is provided with a detachable handle 38 and may be swung into engagement with the jaws 39 and 40, respectively, of the levers 27 and 28, the jaws being faced oppositely, as clearly appears in Fig. 6, so that the shifting lever may be lifted-upwardly into engagement with the jaw of the lever 27 and pushed down into the jaw of the lever 28. These levers are retained in their central position, in which position all of the transmission clutches are outcf engagement, by means of catches preferably in the form of blade springs 41 which are secured to the levers and normally spring into the vertical slot against the shoulder 44 of the slot 32, which actuates the rock shaft9 through the connection describedtothrow the low speed transmission gear into operation.

The parts of my improved control are so arranged that the master clutch is always out of engagement while the transmission clutches are being shifted. To throw the master clutch into engagement, the lever 35 is dropped into engagement with the jaw 45 on the lever 46 of the master clutch control post or rock shaft 47 for controlling the master clutch, the arm beingconnected to the post by means of the sleeve 4'8,see Fig. 6.

he lower end of the control post 47 is provided with an arm 49 which is connected by means of the link 50- to the lever 51. which is pivoted at 52 on the frame.- This lever is connected by the link 53 to the arm 54 on the master clutch controlling rock shaft 11.; Through this connection, the master clutch is actuated. It will be obvious that it cannot be actuated until after the transmission clutch is in engagement.

In changing from the low to theintermediate or high s eed, the controlling lever is swung back and enga 'ed with the, jaw'39 of the lever 27 and the ever' swung back to its initial or inoperative position, which'releases the low speed clutch, and the control lever is then swung down into engagement with the jaw 40 of the lever 28 and the lever swung to the right or left against one of the stops 55, thereby actuating the high or intermediate speed clutches, as desired, as the rock shaft 10 will be actuated through the connections described to throw either the high or the intermediate speed clutches into action. The master clutch is then thrown into engagement by lifting the shifting lever into engagement with the jaw 45 of the lever 46, if the lever 28 has been shifted to the right, and with the jaw 56 of'the lever 57, if the movement has been to the left and swinging the master clutch actuating levers, as before. The lever, 57, is secured to the control post or rock shaft 58 by means of the collar 59. On the lower end' of this post 58 is an arm 60, which is connected by the link 61 to the lever 51, so that the master clutch is actuated through either of these "levers and through this connect-ion of the links 61 and 50, so that the movement of one is transmitted to the other.
